KDY-I-50(10/350µs)

KDY-I-50 series SPDs are Type 1 surge protective devices designed to discharge high current surges without any damage to the back-up electrical equipments. This surge protective device spots its capacity to withstand impulse current with 10/350µs wave form which simulates direct impact coming from a natural lightning current. This SPDs are installed at the entrance point of the building, in the main distribution board of this installation.

*Installation Notes

1. For best performance, mount protector as close t service panel as possible, protector must be connected to a dedicated overcurrent devices sized for the protector's wires.

2. Must install SPD strictly according to the wiring diagram provided

“L1, L2, L3” – live line

“N” – null line

“PE” – Earth wire/Grounding line.

3. Must cut off the power before installation, no hot-line operation is allowed, and better to under the guidance of professional electrician.

4. Green tab, normal work status, Red tab, failure status, need to be replaced Rapidly. 5. Grounding wire should be as thick and short as possible, resistance<10Ω. The grounding line: BVR≥2.5 mm2.
